Problems solved by technology

Since the particleboard impregnation process mainly uses melamine formaldehyde resin solution, the formaldehyde emission of the decorative particleboard is high, which is harmful to people's health
In order to reduce the formaldehyde content, the melamine formaldehyde impregnated resin is usually used to modify or optimize the impregnation process. However, there are few studies to reduce the formaldehyde content of the decorative particleboard by improving the impregnated film paper.

Abstract

The invention discloses a production method of a veneer shaving board, and relates to the technical field of artificial boards. The method comprises the steps of printing, dipping, assembling and hotpressing. According to the production method of the veneer shaving board, oxidized cationic starch and a SAE compound sizing agent are adopted to carry out surface sizing treatment on decorative basepaper, the oxidized cationic starch and the SAE act together, a layer of compact glue film is formed on the surface of the decorative base paper, the air permeability and the void ratio of the decorative base paper are reduced, adsorption of the decorative base paper to an impregnating resin in the impregnating process is reduced, permeation of an an impregnating adhesive solution into the decorative base paper is reduced, the formaldehyde release amount of the impregnating adhesive film paper is reduced, and therefore the formaldehyde release amount of the veneer shaving board in the later period is further reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of wood-based panels, in particular to a method for producing decorative particle boards. 【Background technique】 [0002] Particleboard is a wood-based panel made of wood or other lignocellulosic materials, which is glued together under heat and pressure after applying an adhesive. It is mainly used in furniture, flooring, decoration and other fields. In order to obtain the decorative effect of the pattern, in the production process, the three-dimensional pattern is usually printed on the decorative base paper and then impregnated to obtain the impregnated film paper. The surface of the material presents a three-dimensional pattern. Since the particleboard impregnation process mainly uses melamine-formaldehyde resin solution, the formaldehyde emission of the decorative particleboard is relatively high, which is harmful to people's health. In order to reduce the formaldehyde content, the melamine formalde...
